摘要： A domain key is used to perform chaining decryption with respect to encrypted content key information (ST203-1), and first data is extracted (ST203-2). The extracted first data is compared with partial-check data (ST203-4). The first data as it is encrypted is extracted from the m pieces of encrypted content key information (ST203-6), and a predetermined operation is executed with respect to concatenated data including m extracted check values to generate second data (ST203-8). The second data is compared with whole-check data included in domain key information (ST203-11). If the first data matches the partial-check data (ST203-5) and the second data matches the whole-check data (ST203-12), it is determined that there is not tampering.

摘要： An encryption circuit of a secret key cryptosystem which inputs a plain text and a secret key 4A, inputs R partial keys Kn obtained from the secret key 4A and applies repeatedly R times of round operations to the plain text so that the plain text is encrypted including: registers 4G and 4H which store the values after the round operations of the plain text; a fault detection circuit 1A which decides whether a degenerate fault exists or not by the values of the registers 4G and 4H; and a circuit 1B which invalidates the secret key 4A when the degenerate fault exists in the detection result. The invention provides an encryption circuit which can appropriately respond to a new element of causing occurrence of the degenerate fault, suppress the cost of the hardware, and has a measure against the fault analysis while suppressing an increase in an encryption processing time.

摘要： The metal film of the present invention is a dense film of a single crystal that has very low surface roughness and very good crystal orientation because an arithmetic mean roughness of the surface is not larger than 2 nm and a (111) peak intensity of X-ray diffraction is not less than 20 times the sum of all other peaks. Also the metal oxide film of the present invention is a dense film that includes less oxygen defects and almost no voids therein because a content of a non-oxidized metal is not higher than 1 mole % of a metal component that constitutes the metal oxide and a packing density is 0.98 or higher.
